The 'Twilight' actress topped a poll by Britain's Glamour magazine and was praised by the publication for her progression from ''awkward teen to style queen'' and for always being ''effortlessly on-trend''.

The singer-turned-fashion designer shot up 12 places from last year with the magazine praising the ''adorable co-ordinating looks'' she shares with ''her new favourite accessory'' - nine-month-old daughter Harper.

Britain's Duchess Catherine was honoured for her classic and stylish fashion sense with fourth place.

The magazine said: ''The Duchess of Cambridge's classic elegance has set the high street alight, causing both Zara and Reiss to sell out of her favourite pieces.''
